Specification of Letters Patent.

Patented Feb. 27, 1912.

To all whom it may concern:

Be it known that I, W'ILLIAM FRANoEs GORDON, a citizen of the United States, and resident of Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Locks, of which the following is a full, true, and exact specification.

The principal object of this invention is to provide a padlock of simple, strong and durable construction which is not operable by means of a key, but by a predetermined combination of movements of its parts, controlled by means attached to the lock itself.

In the drawings Figure 1 is a side view of the lock with its parts in locked position, the upper portion being shown in full lines and the lower portion in section substantially on the line y-g/ Fig. 2. Fig. 2 is a side view of the lock with portion broken away. Fig. 3 is a longitudinal sectional view upon the line g/-g/ of Fig. 2 showing the parts in unlocked position and bolt withdrawn from the lock. Fig. 4t is a cross section of the lock upon the line m--m Fig. 1. Fig. 5 is a cross section upon the line a-a of Fig. 1. Fig. 6 is an enlarged detail view of one side of one of the disks. Fig. 7 a view of the other side of one of the disks. Fig. 8 is a plan view of one of the washers. Fig. 9 is an edgewise view of one of the disks with portion broken away.

. The reference character 1 designates a bolt which passes through a staple 2 secured to the jamb of the door and over which is clasped a hasp 3, the hasp being hinged (not shown) to the door in a manner well known. The bolt 1 has one of its ends formed into the loop t which prevents the withdrawal of the bolt l from the staple in any other direction from that in which it entered. The other end of the bolt 1 is reduced at 5, the studs 6 projecting there` from. 7 is the body or casing of the lock, having the perforated ear 7a connected by the chain 7b to the loop 4, and having the circular chamber 8 therein with the longitudinal channels 9. One end of the body 7 is threaded to tit the screw cap l0, which cap has a central opening 11 of the same general contour as a cross sectional view of the reduced portion V5, taken through one of the studs 6. The other end of the body 7 is reduced at 12, which reduced portion lits into the cup 13, having the knob 14. Fartially through the cup 13 passes the stem 15 which is secured to the cup 13 by the pin 16, and ils-circular in cross section. The upper portion of the stem 15 has the enlarged head 17 which loosely fits the circular chamber 8, and is recessed at 18 to receive and form a bearing for the end of the reduced portion 5 of the bolt 1, and also has the stud 18il projecting upwardly therefrom.

19 is a series of cup shaped disks, all of the same construction and dimensions and which loosely fit into the circular chamber 8. Alternating between the disks 19 are the washers 20, having the projections 21, which iit into the longitudinal channels 9 of the circular chamber 8 and hold the washers against rotation, so that any one of the disks 19 may be rotated in the chamber 8 without disturbing the others. Each of the disks 19 has a central opening 211 with an angular portion 22 of the same gen` eral contour as the opening 11 in the cap 10. Each of the disks 19 has projecting from its top the angular headed screw 24 and alsoprojecting into the cup portion thereof a similar screw 23. The head of the screw 23 of each disk lies in the path of the screw 24 of its adjacent disk when the series of disks are in posit-ion as sho-wn in Figs. l and 3. The stud 18a projecting upwardly from the enlarged head 17 is also in the path of the screw 23 of the lowest disk in the series, and which rests upon the enlarged head 17. I provide a top washer 26, of the same diameter as the washers 20 and also having projections corresponding to the projections 21 of the washers 20, to hold the washers against rotation; the washer 26, however, being of considerably heavier material than the washers 20, its function being, in conjunction with the broad projection 27 from the bolt 1, to prevent the turning of the threaded portion of the body 7 in the screw cap 10 when the bolt 1 is in locked position, as Shown in Fig. 1.

28 is a supplemental opening in the disks 19 threaded to receive either of the screws 23 0r 24.

The operation of the lock is as follows: The head 17 is rotated by means of the knob 15, and at some time before a complete revolution of the same is made, the stud 18*l in head 17 contacts with the angular headed screw 23 in the disk adjacent the head 17, and carries that disk around with the head 17; the rotation being continued the angular headed screw 24 in the now moving disk contacts with the screw 23 in the next disk, and so on until all the disks coact and rotate with the head 17. The angular portion 22 of the opening in the disk 19 nearest the cap 10 is now brought into aline- 1 disks are positioned with their angular openings 22 in alinement with the corre sponding opening 11 in the cap 10, as shown in Fig. 3, all the disks 19 being in exactly the position as shown in the enlarged detail view 9. rlhe reduced portion 5 of the bolt 1 can now be readily thrust through the opening 11 in the cap 10 and thence through the now alined openings 22 of the disks 19, and finally the extreme end thereof into the recess 18 in the head 17. By means of the knob 15 the head 17 may now be turned in either direction, which, through the stud' 18a and screws 23 and 24 throws the disks' 19 out of alinement with each other andv prevents the withdrawal of t-he bolt 1 from the lock. It is obvious that the parts may be now unlocked by realining the disks. A suitable index is provided as at A. B. C. Fig. 2, and an indicator 28h, by reference to which the operator is enabled to easily position the disks in a manner well known.

It is evident that a very large number of changes in the combination of turns necessary to aline the disks, simply changing the screws 23 and 24 into dierent relative positions in the disks, all of the openings therefor being threaded alike, and that while I have shown but one extra or supplemental opening 2S, any convenient number may be used.

From the foregoing it will be seen that I have provided an exceedingly strong and durable lock, the body in substantially cylindrical form; that the assembling of the parts is extremely simple, only one pin or rivet (16) being necessary; that while the screw cap 10 may be readily removed when the bolt is withdrawn, the same cannot otherwise be removed and the lock tammay be made byV pered with; that a large number of combinations of movements of the parts is possible to be arranged in order to lock and unlock the parts.

I am aware that many changes in details of construction may readily suggest themselves to others skilled in the art, without departing from the spirit and scope of my invention, and I do not, therefore, wish to be limited to the exact embodiment herein shown and described.

Vhat I claim as new is- 1. A lock comprising a main body having a circular chamber, longitudinal channels opening into said chamber, perforated cup shaped disks of substantially equal diameter within said chamber, relatively thin washers between said disks, a relatively thick top washer, extensions from all of said washers which fit into said longitudinal channels, a screw cap fitted to said main body and having a central opening therein adapted to aline with the openings in said disks, a bolt adapted to pass through said screw cap and said disks when the openings therethrough are in alinement, means for preventing the withdrawal of the bolt when the alinement is destroyed, means for controlling the alinement, an extension from said bolt adapted to coperate with said relatively thick top washer whereby movement of said screw cap is prevented.

2. A lock comprising a main body having a circular chamber, longitudinal channels opening shaped disks of substantially equalY diameter within said chamber, relatively thin washers between said disks, a relatively thick top washer, extensions from all of said into said chamber, perforated cup washers which fit into said longitudinal i from said boltadapted to coperate with said relatively thick top washer whereby movement of said screw cap is prevented.
